Not sure if it applies in this case, but for any case in which it applies:

If the string is only required for saving options/xml files, then it 
should be defined in the editor options unit (maybe?). But IMHO in this 
case you can go with the enum to start with. If the enum is changed at 
any point in the future, the option-loader can have a translation table 
for old entries.
